 Ceramic metal-halide lamp

A ceramic metal-halide lamp (CMH) is a type of high-intensity discharge (HID) lamp that uses a ceramic arc tube to contain the light-producing gases and metal halides. Unlike traditional metal-halide lamps that use quartz tubes, CMH lamps utilize advanced ceramic materials, such as polycrystalline alumina, which allow for higher efficiency, improved color rendering, and better performance overall.
